Product Overview

Built for RC helicopter control, the EMAX ES9254 Ⅱ combines a contactless magnetic encoder, digital control, a coreless brushed motor, and a full metal gear and housing design for responsive and precise operation.

The magnetic encoder provides less than 2° angle error and up to 360° effective control, helping deliver accurate position feedback during flight. Its dedicated RC chip is designed for fast response, with a response speed about twice that of conventional chips.

With a 25T output spline, ES9254 Ⅱ is designed for RC helicopters and offers speed up to 0.035 sec/60° at 8.4V, with torque up to 7.5 kg.cm.

The IP67 protection rating, metal gears, and metal housing provide added protection for outdoor flying conditions. Its compact 40 × 20 × 38.5 mm body weighs 72g and supports 6.0V to 8.4V input.

FAQ

Q: What is the EMAX ES9254 Ⅱ servo designed for?

A: The EMAX ES9254 Ⅱ is a digital magnetic encoder servo designed specifically for RC helicopters. It uses a 25T output spline, a coreless brushed motor, and a dedicated RC chip for responsive helicopter control. Its focus is fast response, precise position feedback, and stable control.

Q: What are the benefits of the magnetic encoder in the ES9254 Ⅱ?

A: The ES9254 Ⅱ uses a contactless magnetic encoder with angle error within 2° and up to 360° effective control. Because the sensing system does not rely on traditional mechanical contact, it provides precise position feedback while reducing mechanical wear.

Q: How fast is the ES9254 Ⅱ RC helicopter servo?

A: At 8.4V, the ES9254 Ⅱ reaches a speed of 0.035 sec/60°, with torque up to 7.5 kg.cm. It also uses a dedicated RC chip designed for faster response, making it suitable for RC helicopter applications where responsive control is important.

Q: Is the ES9254 Ⅱ servo durable and suitable for outdoor flying?

A: Yes. The ES9254 Ⅱ features metal gears, a metal housing, and IP67 protection. The IP67 rating provides protection against dust and water, making the servo suitable for outdoor RC helicopter use and changing flying conditions.

Q: What voltage does the ES9254 Ⅱ support?

A: The ES9254 Ⅱ supports 6.0V to 8.4V input. At 6.0V, it provides 0.05 sec/60° speed and 5 kg.cm torque. At 8.4V, it reaches 0.035 sec/60° and 7.5 kg.cm. The servo weighs 72g and measures 40 × 20 × 38.5 mm.
